Title: Improvements in or relating to a fixed bed gasifier
Inventor: CAMPBELL HUGH LAWRENCE
IPC: C10J3/82
Filed: 1984-04-27
Abstract: A fixed bed gasifier and method of gasification of solid carbonaceous fuel wherein there is provided a fuel supply and inlet means 11 to the gasifier and at least one vertical feed tube 17 in the form of an inverted truncated cone. The feed tube is enclosed in a gaseous exhaust gas conduit 23 and the bulk of gases from the gasifier passes upwardly through descending coal in the feed tube and through apertures 25 in the wall of the feed tube into a chamber 27 formed between the in feed tube and exhaust gas conduit while a portion of hot gases from the gasifier passes directly into the chamber 27 to maintain the temperature of the gases when combined in the chamber above their dew point. The combined gases are tangentially discharged from the chamber through a pipe 29 or 29' and, when a plurality of feed tubes are provided, the discharged gases combined and removed through a common offtake conduit 31. <IMAGE>

Title: Breathing apparatus
Inventor: WRIGHT DR CHRISTOPHER JOHN
IPC: A62D9/00
Filed: 1984-06-13
Abstract: A catalyst device for purifying a carbon monoxide containing atmosphere, e.g. for use in breathing apparatus for underground workers, comprises a chamber containing a catalyst bed for low temperature oxidation of carbon monoxide and having an inlet for permitting ingress of air from the atmosphere and an exit for connection to the face of the user, e.g. by means of a face mask. When the mask (for example) and the chamber are in pneumatic connection, inhalation through the mask causes air to enter the chamber via the inlet, to contact the catalyst bed for catalytic oxidation of CO therein, if present, and thence pass to the mask. In order to provide resistance to deactivation by water vapour and obviate the need for a drying agent, the catalyst bed comprises one or more platinum group metals in combination with tin (IV) oxide e.g. Pt and Pd in combination with tin (IV) oxide.

Title: Transfer of articles from one conveyor to another
Inventor: PARK DAVID B
IPC: B65G15/02
Filed: 1984-10-10
Abstract: A conveyor apparatus conveys magnetically attractive articles. The apparatus comprises first and second conveyors (26,14) with the latter being driven faster than the former. A magnet (36) is arranged for magnetically drawing the articles downwardly toward the first conveyor to increase traction therewith. The first conveyor intersects the second conveyor as viewed in side elevation and forms an angle A of less than 180 degrees therewith so that during the transfer of an article, the article contacts the first and second conveyors mainly by line contact and is drawn against the first conveyor by the magnet, so that the first conveyor maintains control over the speed of the article during transfer. The magnet may also be arranged to attract the article toward the second conveyor after the transfer is complete. The first and second conveyors are driven by a common motor such that the speeds of those conveyors varies proportionally. <IMAGE>

Title: Radio frequency heating of wire
Inventor: DYOS GORDON THOMAS
IPC: H05B3/00
Filed: 1984-11-07
Abstract: A wire (4) or the like is heated by supplying radio frequency electrical energy to the wire at spaced locations therealong by the use of tubular electrodes (3) through which the wire (4) passes, thereby to capacitively couple radio frequency electrical energy into the wire (4) between the electrodes (3) to cause heating of the wire (4). Such method and apparatus has the advantages that it is unnecessary to form the wire into a loop for inductive coupling of the energy into the wire.

Patent GB-2159963-A (GB)
Title: Measuring rate of change of frequency
Inventor: WARIN JOHN WILLIAM
IPC: H02J3/38
Filed: 1985-04-26
Abstract: A repeatedly updated signal indicative of rate of change of frequency in an electricity supply system is obtained by repeatedly counting at 10 a number such as ten of cycles of a phase of the supply from 24 to determine an indexing period at 12 during which high frequency clock pulses from 14 are counted at 16. Clock pulse counts for successive indexing, periods are stored in respective locations of store 18, the index count from 12 serving to remove the oldest and add the newest count from 16. The difference between the oldest stored count and the median stored count and between the median stored count and the newest stored count are substrated at 20 to give the rate of change of frequency signal at 22. To derive the indexing periods 12 related to the supply phase input to circuit 24 but insensitive to spikes thereon, the circuit 24 gates oscillator pulses from 28 to counters 30, 32 during positive and negative half cycles. These each reset after a predetermined count and cause a bistable 34 to set and reset. This generates in effect a squared and delayed version of the input to be counted down at 12. <IMAGE>

Filed: 1986-08-26
Abstract: Disclosed is an improved method for coating a zinc surface comprising treating said surface with an aqueous, acidic solution containing: (a) about 0.5 to about 4 percent phosphate ion; (b) an ion selected from the group consisting of zinc ions, manganese ions, and mixtures thereof, said ions being present at a level sufficient to form dihydrogen phosphate with substantially all of said phosphate ions; and (c) about 0.01 to about 1 percent complex fluoride ions; wherein the weight:weight ratio of complex fluoride ions:chloride ions in said solution is at a value of about 8:1 or greater. It is preferred that the ratio complex of fluoride ion to chloride ion (F-:Cl-) in said solution to be maintained at a value of greater than about 8:1, preferably greater than about 10:1, and more preferably greater than about 14:1. The select weight:weight complex fluoride:chloride ratio substantially eliminates the abnormal crystal growth frequently found in treated surfaces while at the same time reduces the need for excess fluoride.

Title: Line sensing self actuating bell unit
Inventor: GUILLIATT JAMES DAVID
IPC: G08B29/06
Filed: 1988-03-17
Abstract: The bell unit has all of its input connections monitored to detect breaks in conductor continuity and short circuits between the conductors. A break in the supply conductors OV, 12V causes a relay RLY1 to be de-energised and the bell to be energised from a battery. A break in a tamper return conductor TR or the opening of a tamper switch causes a transistor T2 to be turned off, via a transistor T1, which again causes the relay to be de-energised. A triggered conductor T carries a monitoring current and if this extends outside a given range the transistor T2 is again turned off. <IMAGE>

Abstract: 888,245. Priming. LINDE'S EISMASCHINEN A.G. GES. FUR. Oct. 17, 1960 [Oct. 17, 1959], No. 35471/60. Class 7(5). An engine priming device comprises a resilient deformable body 1 defining first and second chambers 2, 3 intercommunicating through a passage 6 so designed that it is capable of being closed by deformation of the body, the first chamber including a normally closed aperture 7 capable of being opened by deformation of the body to allow introduction of a priming agent and the second chamber including means 4 for operative connection of the device to the engine. Thus pressure may be applied to, the passage 6 manually this pressure closing the passage 6 and at the same time opening the aperture 7. The priming agent can then be introduced into the chamber 2 whereafter the pressure is removed, thus allowing the passage to re-open and the priming agent to pass into the chamber 3. The lower end of the chamber may have an internal thread or be formed to enable it to be pushed into a bore or pressed over a tube. The Specification refers to a liquid or powder additive or priming, agent which is particularly prone to combustion such as for example an ether-paraffin mixture.
